i have several videos since today morning but this video is 1000 times better than all other waste videos. !!!! now i got some idea about fourier transform in image analysis... love u !!!!!!!!!!!!!!!!
I've just recently discovered your channel and I must say you're doing an amazing job! Keep it up! One thing that bothers me here is when you're explaining the conversion from time domain to frequency domain at 5:55 - the Y axis should be an amplitude value, thereafore the representation of a sine wave in frequency domain should not be a dot but a straight line with corresponding amplitude value, am I right? Cheers!
You are absolutely right, the representation of sine wave in frequency domain is a vertical line at the specific frequency with a height that reflects the amplitude of the wave. It appears that at around 5 minutes in my video I focused on pointing out the frequency locations and not on the amplitude. This is what happens when I try recording a video in one go, I tend to overlook certain things or assume people would build on the thought I had at the moment :)
i have quick doubt at center u said that it will be having low frequency component does is it mean the number of occurences of a specific intensity? for example if we have white colour at the middle does it mean it has less number of intensity values related to white colour??
Does not matter if you multiply the log with 20 but it is just out of habit. Here is a bit more explanation: murray.cds.caltech.edu/index.php/Why_is_dB_defined_as_20log_10%3F
Hello sir Your doing great job, i am doing my bachelor in electronics and communication, i was interested in image processing. If possible Please help me any certification course and how can i get a job in this field? Thank you in advance :)

Thank you so much for ur clear explanation. some topics are difficult to understand until watching lectures like yours. u r great teacher
Thanks and welcome

it's finally here!! thank you!!

Maybe, you would like to add, why we are multiplying the constant 20 * np.log?

@@DigitalSreeni Thanks for the answer sir.
😀Thank you 😍
